Back at Google I/O 2014, we learned about a pretty neat feature called Backdrop that gives your Chromecast a little more pizazz with localized weather, news, and photos. It turned out to be a bit of a tease, because Google waited until earlier today to actually enable it through an update to the Chromecast app for our phones. During the same presentation, another feature called "Guest Mode" was announced promising to allow visitors to cast from their devices to a Chromecast in the same room without being on the same Wi-Fi network.

One last app came rolling in at the tail end of update Wednesday. This time, we've got a relatively small update to Android Device Manager, Google's answer for lost or stolen phones. The changelog hasn't been posted on the Play Store, but a quick teardown told us everything we needed to know. There's a new callback feature that makes contacting the owner a one-touch operation.

Android Device Manager is already a great way to ensure you can locate, lock, or wipe your phone if you lose it. You can remotely access it from your tablet or any full computer, but what if you're out and about and don't have any spare technology handy, and no way to connect it? Google has delivered a solution in the form of the latest Android Device Manager update. Now any Android device with ADM can allow guests to log in, with full access to remote location, ringing, locking, and wiping.

Firefox Beta users, listen up. It's time to whip out your phone and check for updates. The slightly less stable version of Mozilla's mobile browser has made the leap to version 25, and it's picked up a few new features along the way. The most visible new feature is a new guest browsing mode that lets you safely hand the phone over to grandma without her getting a closer look at your browsing history than either of you ever wanted.
